Update README.md Contribution.md and CODE_OF_CONDUCT.md

[YTeyddie22]

The current contribution documentation could be more comprehensive to better guide contributors. The documentation outlines key information such as the project structure but lacks detailed guidelines on key aspects like creating issues, submitting pull requests, and reviewing contributions.

A robust contributing guide could include:

• Clear instructions on how to create and label issues.
• Steps for getting an issue assigned and starting work on it.
• Guidelines for submitting pull requests, including linking issues and avoiding force-pushes.
• A section on effectively reviewing pull requests with DOs and DON'Ts.

The project also does not have an established Code of Conduct. Implementing one could be highly beneficial in creating a safe, inclusive, and respectful environment for all contributors. I suggest adopting something similar to the Contributor Covenant Code of Conduct, which has been widely recognised and successfully implemented in many OSS projects.
An example would include the following topics:

• Our Pledge
• Our Standards
• Enforcement Responsibilities
• Scope
• Enforcement guidelines

Adding such detailed information will help new contributors get up to speed faster and, maintain consistency and quality in their contributions.

The link for CODE_OF_CONDUCT in README.md is also broken.

Please give feedback on this when you find the time and if approved, assign me the issue

Thanks!
